under normal atmospheric conditions iron rusts to form hydrated oxides, a process that occurs in two steps: first, iron dissolves in the acid solution produced by the moisture and the carbon dioxide of the air, to form ferrous iron--i.e., iron (ii)--and liberate hydrogen; second, oxygen from the air oxidizes the ferrous iron to form hydrated iron .

The electron configuration of Fe 3+ is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5 where 5 unpaired electrons are present. Therefore, hematite can be separated from a mixture using high-intensity magnetic separation methods which use magnetic fields with intensity ranging from 0.02-4.0 Tesla. Hematite has a metallic gray appearance.

Iron oxide electrolysis to produce iron metal has been known since the pioneering work of Lloyd in 1929 1 and LeDuc et al. in 1959. 2 A process was patented by Offroy in 1974. 3 However, as the blast furnace is an efficient and mature technology, this work has been very limited in scope and, in particular, the details of iron oxide reduction have received very little attention.

Examples of metallic minerals include bauxite, hematite, iron ore, aluminum, gold and silver. In addition to this, these are ductile and malleable in nature, which means that they can be drawn into wires and beaten into sheets respectively. Metallic minerals can be further divided into Ferrous Minerals and Non-ferrous minerals.

Iron is magnetic in its α form. The α form occurs below a special temperature called the Curie point, which is 770 °C. Iron is paramagnetic above this temperature and only weakly attracted to a magnetic field. Magnetic materials consist of atoms with partially-filled electron shells. So, most magnetic materials are metals.
